Oh BGs.
non-rated, anything goes. you can pick a goofy team if you want. 5 druids or something.

Shodokan is pretty spot on those points. I am pretty biased on DK + 4Rets , as DK + 4Rets can do heroic. But that's just me.

I am currently on warrior for that 1 shot macro burst trick. Once that's nerfed, warrior is out.
